In passing, reflecting on the fact that on his way to the White House Prez thought it would be a good idea to primary Bobby Rush, it makes it easier to understand why he has turned out such a disappointment.

We may have collectively taken too much pride in electing a president of partially African ancestry, but surely we cannot be doing all that badly when the Chicago Panthers' Minister of Defense is able to stand astride the House Floor like a Collusus.

Long live Bobby Rush! Long live the Black Panthers! All power to the people!

More than you ever wanted to know about this rule (back to 1837 and before,) here's a good article from late 2010, Miami Herald's "Truth-o-meter" column that went into depth, In pursuit of an answer regarding newly elected Rep Frederica Wilson, a true "hat lady," including detailed history of the rule and trying to get a straight answer from contemporary House rule sticklers:

Congresswoman-elect Frederica Wilson says hat ban started in 1800s but can be waived

as "half true," based on many things, including this which surprised me:

Even the late Rep. Bella Abzug (D-N.Y.) couldn't sport her trademark broad-brimmed hats when she served during the 1970s."

The answer to your question , btw, is at the end:

An aside: we wondered if the current hat ban rule would prohibit religious Jews from wearing yarmulke or Muslim women from wearing the hijab or headscarf. Steel, Boehner's spokesman, said in an e-mail: "The rule regarding hats has never been interpreted to apply to religious headcoverings."

I sort of enjoyed reading the whole thing, obsessive cultural history buff that I am.

Edit to add from the article: Unlike the House, the Senate doesn't have a formal written rule banning members from wearing hats. "People don't wear hats in the Senate," said Senate historian Donald Ritchie. "The Senate sort of adheres to an unofficial dress code but it's not specifically in the rules." Sort of the reverse of what most would think at first, but then if one remembers that the Senate was a sort of gentlemen's club from the start while the House was for the rabble, where some might becoming to town from some godforsaken place where denizens were not acquainted with urban manners....

[....] Last month, Jared Kushner announced the Administration’s support for the bill in a Wall Street Journal op-ed, writing that the six million Americans in local and federal prisons are included among “the forgotten men and women” that Trump vowed to fight for during his Presidential campaign.. “Get a bill to my desk, and I will sign it,” Trump promised. The House passed the bill this week.

President Trump on Thursday canceled a planned summit next month with North Korean leader Kim Jong Un, citing “tremendous anger and open hostility” from the rogue nation in a letter explaining his abrupt decision.

“I feel it is inappropriate, at this time, to have this long-planned meeting,” Trump said to Kim in a letter released by the White House on Thursday morning.

The summit had been planned for June 12 in Singapore.

In his letter, Trump held open the possibility that the two leaders could meet at a later date to discuss denuclearization of the Korean peninsula, which Trump has been pushing.

"President Trump’s unprecedented meeting on Monday with the FBI director and deputy attorney general regarding a case in which he is directly involved may turn out to be the defining moment of his presidency and for his party. Bob Bauer at the Lawfare blog writes:

North Korea is threatening to reconsider Kim Jong Un’s participation in a summit with President Trump next month, saying it is up to the United States to decide whether it wants to “meet us at a meeting room or encounter us at nuclear-to-nuclear showdown.”

Stacey Abrams just one the Democratic Gubernatorial race in Georgia by roughly 3:1. She could become the first black and first female Governor of Georgia. It looks like the Republican candidate will be chosen after a runoff election since no one reached 50% of the vote.

Evans argued that Democrats could win by appealing to moderate Republicans. Abrams argued that the party needs to focus on disaffected Democrats. Abrams won. Abrams even won Democrats in northern Georgia with small minority populations.

Kendrick Lamar brought on a white fan onstage to rap along with his song “m.A.A.D. City”. When the fan rapped the song as written, repeating the N-word three times, Lamar halted the performance. He told the fan that she could not use the word. She apologized. He gave her a second chance. She almost rapped the word again, the crowd was not having it. Lamar ushered the fan off stage and continued the performance.

The audience responded negatively to the white fan using the words on stage. She lost the crowd with the first use of the words. Some did point out that she was just rapping the words as written.
